PUMP.

To all whom. it may concern:

Be it known that I, ISAAC R. S'ron'r, citizen of the United States, residing at Walla lValla, in the county of Walla Valla and State of Washington, have invented certain f stream.

Further objects and the advantages of my invention will be apparent to those skilled in the art from the following description in which reference is made to the accompanying drawing, forming a part of this specification, and in which,

Figure 1 is an elevation of my improved device. Fig. 2 is an enlarged sectional view through the upper valve portion of my device. Fig. 3 is a similar view through one of the pump barrels and its valve. Fig. 4 is an enlarged detail sectional view of the pump barrel valve shown in Fig. 3, and, Fig. 5 is a similar View of my preferred connection between the casings forming the chambers of the inlet and outlet air valves and the piston and connecting chambers.

In the practical embodiment of my invention, I provide a pair of pump barrels 1 and 2, both of which are to be submerged well below the water line, as shown in Fig. 1, and provided in their bases with inwardly opening intake valves 3, (Fig. 3), surrounded by a mesh or perforated m'etal straining cylinder 4. A pipe 5 leading upwardly alongside the superposed vertical alined barrels 1 and 2, is connected to the lower ends thereof by fittings 6, in which are located outwardly opening valves 7, said pipe being extended to the surface and constituting the water outlet pipe.

Mounted upon the upper end of each of the pump barrels 1 and 2 are pump valves 8, one of which is illustrated in Fig. 4. Each of these pump valves comprises a tubular casing 9, which, by its` contracted lower stand portion 10, also tubular, communicates within the pump barrel upon which it is secured, through an opening in the upper end of the latter. The upper end of the stand portion forms a valve seat 11, at

the base of a short cylinder 11a, for a downwardly closing valve 12, connected by means of a valve rod 13, to a iloat 14, arranged within its pump barrel a short distance above the level of its outlet fitting 6, and wit-hin a hood 15 opening downwardly and secured to the barrel wall, and through which said valve rod extends. The stand portion 10, also supports a hood 16, within casing 9, and upon legs 17 which guide valve 12 in its movements. The upper end of hood 16 forms a valve seat for a needle valve 18, and communicates with a pipe 19, extending upwardly within a pipe 20, from the upper end of casing 9. The hood 16 is also provided with an opening 21 through its wall just below the seat of valve 18, and casing 9 may also be provided with a pipe 22, leading from the upper portion downwardly through the upper portion of the pump barrel. The needle valve 18 is provided with a plate 23, supported therefrom, and spaced therebelow, by rods 24, said plate 23 having a central aperture through which the upwardly projecting end 25 of valve rod 13 above the valve 12, extends, said projecting end 25 having a nut 26 thereon above said plate 23. Thus, as shown, when the conical valve is in the open position (Fig. 4), raised thereto by float 14, it is within the lower end of hood 16, and protected from the action of the air which flows downwardly through casing 9, from air pipe 20, into the pump barrel through the tubular stand 10. Also as shown, in this position, the upper end 25 of valve rod 13, presses the needle valve 18 firmly into its seat in the lower end of pipe 19, closing port or opening 21. It will be seen that when the water level in the pump barrel falls, the float 14 descends, pulling down valve 12 into the path of the air which rmly closes the same in cylinder 11a and upon seat 11, and that the nut 26 upon the valve rod end 25, strikes the plate 23 in its downward movement and pulls the needle valve 18 slightly from its seat, sufficient to uncover port or opening 21, whereby the air in pipe 2O and casing 9 is let into pipe 19 and also the air in the pump barrel through pipe 22 having therein a valve 27 opening upwardly toward casngs 9.

The upper ends of the outer air pipes 20 and 28 of the pump barrels 1 and 2 respectively, lead from the upper and lower chambers 29 and 29a respectively of the inlet air valve 30, the central chamber 31 of which iS separated from said upper and lower chambers 29 and 29a, by centrally apertured disks 32 and 33 respectively, forming valve seats as hereinafter described.

Pipes 2O and 28 are connected by branch pipes 34 and 35 respectively to the upper and lower chambers 36 and 37 of the outlet air valve 40, the central chamber 38 of which, as in the case of the inlet air valve, is separated from said upper and lower chambers 36 and .37, by centrally apertured disks 39 and 39a, forming valve seats.

Inlet and outlet air pipes 41 and 42 lead to and from the central chambers 31 and 38 of air valves 30 and 40 respectively.

The inlet and outlet air valves 30 and 40, which are superposed and vertically alined as shown, are connected, by a tubular casing 43 extending between their lower and upper chambers 29ar and 36 respectively. Said valves and 40 also have tubular casings 44 and 45 vextending' upwardly and downwardly therefrom respectively, and connecting their` upperand lower chambers 29 and 37 respectively with piston chambers 46 and 47. The valves 30 and 40, tubular casings 43, 44 and 45, and piston. casings 46 and 47 are thus longitudinally in a series, and have .eachv of said disks.

extending therethrough a valve rod 48. lVithin valve 30 rod 48 is provided with a valve 49 i-n chamber-31 between disks 32 and 33 and capable of seating in the apertures of Vithin valve rod 48 is provided with valves 50 and 51 respectively located in chambers 36 and 37 and adapted to seat in the apertures of disks 39v and 39, one at a time. Thus as shown in (Fig. 2, when valve 49 is seated in disk valve 51, is seated in disk 39a, while upon longitudinal movement of rod 48 to seat valve 49 in disk 33, valve 51 will be moved away from disk 39a and valve 50 seated-in disk 39. The means for moving` rod 48 longitudinally comprise piston heads 52 and mounted upon the ends thereof in piston chambers 46 and 47, which chambers 46 and 47 have air pipes 54 and 55 and pipes 56 and .57 .leading to the upper. and lower portions thereof respectively.

As shown in Fig. 2, valve rod 48 is in two longitudinal sections, the lower end of the upper section` being provided with a depend- Ying sleeve 48a, screwed thereon, and having an aperture in its lower end through which the upper end of the lower section projects and is provided within said sleeve with a head 48h. Thus the several valves may seat Vuniformly and evenly.

The u per pipes 54 and. 56 of chambers 46 and 4 respectivelyare connected by vertical an'd horizontal pipes. 58 and 59, the latter of which has a minute aperture 60, to the upper end of the inner air pipe 61 of the lower pump barrel valve 8, which'fextends upwardly within, the air supply pipe 28 thereof, while the lower pipes 55 and 57 of chambers 46 and 47 are connected by vertical and horizontal pipes 62 and 63, the latter of which has a minute aperture 64, to the inner air pipe 19 of the upper pump barrel valve 8 which extends upwardly within the air supply pipe 20 thereof. Thus, referring now to Figs. 2 and 3, it will be seen that the parts are in Josition corresponding to the exhausting of the water from .the lower pump barrel 2, air being admitted from air inlet pipe 41 through disk 33 of the inlet valve 30, and through the lower pump barrel supply pipe 28, and air being exhausted from the supply pipe 20 of the upper pmnp barrel, through disk 39 of the outlet air valve and through the outlet air pipe 12. As soon as the water level in the lower pulnp barrel falls to an extent permitting` the tloat disk 33, and valve 50 in disk 39, and unseating valve 51, thus dctieeting the inlet air through disk 32 into the upper end ot the upper pump barrel supply pipe 20, and opening communication between the lower pump barrel supply pipe 28, b v its branch 35. through. disk 39u, to the outlet air pipe 42. The minute apertures 60 and 64 in pipes 59 and 63 gradually relieve the pressure in their respective piston operating pipes. the valve rod 48 being held balanced in either of its positions, to which it is moved, by the inlet and outlet air between the valves 49, 5t) and 51 and pistons 65, 66 and 67 secured upon said rod. 48 within the casings 43, 44 and 45 respectively, which pistons 65, 66 and 67 are, as shown, ot' less area than the valves 49, 5t) and 51.

Thile in Fig. 2, I have shown a conventional form of connection between the casings forming the several valve chambers. my preferred connection is shown in Fig. 5, in which the casing 68 corresponds to the casing forming chamber 31 in Fig. 2, and casing 69 corresponds to the easing forming chamber 29 in said figure. Casing 68 is provided just below its end with an internal circular flange 70, which supports thc apertured disk 71, corresponding to disk 32 in Fig. 2, and is externally threaded. Casing 69 which is of smaller diameter than casing 68, is provided with an internal circular flange 72, resting upon disk 71, and is externally threaded for the reception of a metallic packing ring 73 screwed down tight against the end of casing G8. A coupling sleeve 74, having one inwardly curved circular edge 75 and internally threaded, is screwed upon the external threads of the casing 68, and engages with its said curved edge, the packing ring 73, to hold the casings together in air-tight relation. y
